Description

La présente invention se rapporte à une pièce d'horlogerie mécanique dont le mouvement est muni d'un mécanisme de chronographe comprenant des bascules et une roue à colonnes ainsi qu'à un tel mécanisme de chronographe.The present invention relates to a mechanical timepiece whose movement is provided with a chronograph mechanism comprising flip-flops and a column wheel as well as such a chronograph mechanism.

Plus particulièrement la présente invention a pour objet un mécanisme de chronographe comportant une roue à colonnes commandant les déplacements d'une bascule d'embrayage munie d'un dispositif de réglage particulier de l'amplitude du déplacement de cette bascule d'embrayage. Ce dispositif de réglage détermine plus particulièrement la pénétration de la denture d'une roue intermédiaire, pivotée sur la bascule d'embrayage, dans la denture de la roue de chronographe. Cette pénétration de la denture de la roue intermédiaire dans la denture de la roue de chronographe est déterminante pour la bonne marche du mécanisme de chronographe.More particularly, the present invention relates to a chronograph mechanism comprising a column wheel controlling the movements of a clutch rocker provided with a particular adjustment device of the amplitude of displacement of the clutch rocker. This adjustment device determines more particularly the penetration of the toothing of an intermediate wheel, pivoted on the clutch rocker, in the toothing of the chronograph wheel. This penetration of the toothing of the intermediate wheel into the toothing of the chronograph wheel is decisive for the proper operation of the chronograph mechanism.

Dans un mécanisme de chronographe à roue à colonnes habituel, la bascule d'embrayage portant la roue intermédiaire est pivotée concentriquement à une roue entraîneuse en prise avec la roue intermédiaire. Lorsque le bec, ou extrémité libre, de la bascule d'embrayage est en contact, sous l'effet de son ressort de rappel, avec une des colonnes de la roue à colonnes, la roue à colonnes la roue intermédiaire n'engrène pas avec la roue de chronographe. Par contre, lorsque le bec de la bascule d'embrayage tombe entre deux colonnes de la roue à colonnes, la denture de la roue intermédiaire s'engage dans la denture de la roue de chronographe pour entraîner celle-ci. Le degré de pénétration de ces dentures est indispensable malgré la précision de ces dentures du fait de petits modules, des tolérances de fabrication ainsi qu'aux mal ronds des deux roues. Ce degré de pénétration est déterminé par la position d'un excentrique contre lequel vient buter la bascule d'embrayage, excentrique situé entre l'axe de rotation de la bascule d'embrayage et le bec de cette bascule. Un tel réglage du déplacement de la bascule d'embrayage d'un mécanisme de chronographe à roue à colonnes est connu notamment du document EP 1 316 863 ou du document CH 5821 .In a conventional column wheel chronograph mechanism, the clutch rocker carrying the intermediate wheel is pivoted concentrically to a driving wheel engaged with the intermediate wheel. When the spout, or free end, of the clutch rocker is in contact, under the effect of its return spring, with one of the columns of the column wheel, the column wheel the intermediate wheel does not mesh with the chronograph wheel. By cons, when the nose of the clutch rocker falls between two columns of the column wheel, the toothing of the intermediate wheel engages in the toothing of the chronograph wheel to drive it. The degree of penetration of these teeth is essential despite the precision of these teeth due to small modules, manufacturing tolerances as well as poorly rounded two wheels. This degree of penetration is determined by the position of an eccentric against which abuts the eccentric clutch lever located between the axis of rotation of the clutch rocker and the tip of this rocker. Such a displacement setting of the clutch rocker of a column wheel chronograph mechanism is known in particular from the document EP 1 316 863 or document CH 5821 .

Le but de la présente invention est de réaliser un dispositif de réglage de la pénétration de la denture de la roue intermédiaire dans la denture de la roue de chronographe qui soit plus précis. Un autre but de la présente invention est de supprimer l'excentrique réglant la course de la bascule d'embrayage pour simplifier le mécanisme et son montage. En effet l'excentrique étant chassé par un cône dans un trou rond, il nécessite une opération manuelle de mise en place avec un équarrissoir par l'horloger. L'invention a pour objet un mécanisme de chronographe comportant un dispositif de réglage de l'amplitude du déplacement de la bascule d'embrayage d'un mécanisme de chronographe à roue à colonnes, précis et plus simple que les dispositifs décrits ci-dessus et qui se distingue par les caractéristiques énumérées à la revendication 1.The object of the present invention is to provide a device for adjusting the penetration of the toothing of the intermediate wheel in the toothing of the chronograph wheel which is more precise. Another object of the present invention is to remove the eccentric adjusting the stroke of the clutch rocker to simplify the mechanism and its mounting. Indeed the eccentric being driven by a cone in a round hole, it requires a manual operation of setting up with a squared by the watchmaker. The invention relates to a chronograph mechanism comprising a device for adjusting the amplitude of the displacement of the clutch rocker of a column wheel chronograph mechanism, accurate and simpler than the devices described above and distinguished by the features enumerated in claim 1.

Le dessin annexé illustre le mécanisme de chronographe comportant le dispositif de réglage de l'amplitude de déplacement de la bascule d'embrayage soit de la pénétration de la denture de la roue intermédiaire dans la denture de la roue de chronographe.The accompanying drawing illustrates the chronograph mechanism comprising the device for adjusting the amplitude of displacement of the clutch rocker or the penetration of the toothing of the intermediate wheel in the toothing of the chronograph wheel.

Comme on le voit sur les figures du dessin le mécanisme de chronographe comporte entre autres une roue à colonnes 1 comportant huit colonnes 2 uniformément réparties autour de sa périphérie et une denture d'entraînement en dent de loup 3 comportant seize dents. Cette roue à colonnes est pivotée sur un axe 4 creux fileté intérieurement, solidaire du pont 5. Cette roue à colonnes 1 comporte un chapeau 6 reposant sur l'axe creux 4 et pivoté autour de celui-ci. Une vis 7 vissée dans l'axe creux 4 permet de bloquer le chapeau 6 de la roue à colonnes 1. La partie périphérique 17 de ce chapeau 6 s'étendant au-dessus des colonnes 2 de la roue à colonnes constitue aussi une sécurité limitant le déplacement axial de la roue à colonne 1 en cas de chocs.As can be seen in the figures of the drawing, the chronograph mechanism comprises, inter alia, a column wheel 1 comprising eight columns 2 uniformly distributed around its periphery and a wolf tooth 3 toothing comprising sixteen teeth. This column wheel is pivoted on an internally threaded hollow shaft 4 secured to the bridge 5. This column wheel 1 comprises a cap 6 resting on the hollow axis 4 and pivoted around it. A screw 7 screwed into the hollow shaft 4 makes it possible to lock the cap 6 of the column wheel 1. The peripheral part 17 of this cap 6 extending above the columns 2 of the column wheel also constitutes a limiting safety device. the axial displacement of the column wheel 1 in case of shocks.

La roue à colonnes 1 est entraînée pas à pas en rotation par un cliquet non illustré en prise avec la denture 3, cliquet commandé par une bascule de commande non illustrée actionnée traditionnellement par un poussoir non illustré.The column wheel 1 is driven stepwise in rotation by an unillustrated pawl engaged with the toothing 3, pawl controlled by a non-illustrated control lever actuated traditionally by an unillustrated pusher.

Le mécanisme de chronographe comporte encore une bascule d'embrayage 10 pivotée autour d'un axe 11 concentriquement à une roue entraîneuse 12 engrenant en permanence avec une roue intermédiaire 13 pivotée sur une partie médiane de cette bascule d'embrayage 10. A son extrémité libre la bascule d'embrayage 10 se termine par un bec 14 coopérant avec la roue à colonnes 1. Suivant la position angulaire de la roue à colonnes 1 le bec 14 prend appui contre la face périphérique d'une colonne 2 de la roue à colonnes ou tombe entre deux colonnes 2 adjacentes.The chronograph mechanism further comprises a clutch lever 10 pivoted about an axis 11 concentrically to a driving wheel 12 meshing permanently with an intermediate wheel 13 pivoted on a central portion of the clutch rocker 10. At its free end the clutch rocker 10 ends with a spout 14 cooperating with the column wheel 1. According to the angular position of the column wheel 1 the spout 14 takes bearing against the peripheral face of a column 2 of the column wheel or falls between two adjacent columns 2.

Lorsque le bec 14 prend appui, sous l'effet d'un ressort, non illustré, agissant sur la bascule d'embrayage 10, contre la périphérie d'une colonne 2 de la roue à colonne 1, le chronographe est à l'arrêt, la denture de la roue intermédiaire 13 étant dégagée de la denture d'une roue de chronographe 15 (fig. 1,3 et 6).When the spout 14 is supported, under the effect of a spring, not shown, acting on the clutch rocker 10, against the periphery of a column 2 of the column wheel 1, the chronograph is stopped , the toothing of the intermediate wheel 13 being disengaged from the toothing of a chronograph wheel 15 ( Fig. 1 , 3 and 6 ).

Lorsque le bec 14 tombe entre deux colonnes 2 (fig. 2,4 et 7) la denture de la roue intermédiaire 13 pénètre dans la denture de la roue de chronographe 15 pour son entraînement. Le bec 14 de la bascule d'embrayage vient buter par sa face d'appui 16, de préférence courbe, contre la face périphérique 17 du chapeau 6 pour limiter la course de la bascule d'embrayage et donc la pénétration des dentures des roues intermédiaires et de chronographe.When the spout 14 falls between two columns 2 ( Fig. 2 , 4 and 7 ) the toothing of the intermediate wheel 13 enters the gearing of the chronograph wheel 15 for its drive. The spout 14 of the clutch rocker abuts by its bearing surface 16, preferably curved, against the peripheral face 17 of the cap 6 to limit the stroke of the clutch rocker and thus the penetration of the teeth of the intermediate wheels and chronograph.

En effet, le bec 14 comporte dans sa partie terminale portion 18 une plus faible épaisseur que celle de la bascule formant ainsi une face d'appui 16.Indeed, the spout 14 has in its end portion 18 a smaller thickness than that of the rocker thereby forming a bearing surface 16.

Pour permettre un réglage de l'amplitude du déplacement de la bascule d'embrayage 10, c'est-à-dire de la pénétration des dentures des roues intermédiaires 13 et de chronographe 15, la surface périphérique 17 du chapeau 6 de la roue à colonnes 1 est ovale et non pas circulaire. Ainsi, la position angulaire du chapeau 6 sur la roue à colonnes 1 détermine la position angulaire embrayée de la bascule d'embrayage 10. Pour régler cette position il suffit de dévisser légèrement la vis de fixation 7 du chapeau 6 et de déplacer celui-ci angulairement à l'aide d'un outil comportant des doigts venant se loger dans des perçages 19 que comporte le chapeau 6. Une fois la position idéale de la bascule 10 réglée la vis de fixation 7 est serrée.To allow adjustment of the amplitude of displacement of the clutch rocker 10, that is to say of the penetration of the teeth of the intermediate wheels 13 and chronograph 15, the peripheral surface 17 of the cap 6 of the wheel columns 1 is oval and not circular. Thus, the angular position of the cap 6 on the column wheel 1 determines the engaged angular position of the clutch rocker 10. To adjust this position simply unscrew slightly the fixing screw 7 of the cap 6 and move it angularly using a tool having fingers that are housed in holes 19 that includes the cap 6. Once the ideal position of the rocker 10 set the fastening screw 7 is tightened.

Ainsi, dans cette réalisation le dispositif de réglage de la course de la bascule d'embrayage est constitué par la surface périphérique ovalisée 17 du chapeau 6 de la roue à colonnes 1 coopérant avec la face d'appui 16 du bec 14 de la bascule d'embrayage 10.Thus, in this embodiment the device for adjusting the stroke of the clutch rocker is constituted by the oval peripheral surface 17 of the cap 6 of the column wheel 1 cooperating with the bearing face 16 of the spout 14 of the rocker d clutch 10.

Le chapeau 6 a donc trois fonctions, une fonction esthétique, une fonction de limitation des déplacements axiaux de la roue à colonnes 1 en cas de chocs et une fonction de réglage de la pénétration des dentures des roues intermédiaires 13 et de chronographe 15.The cap 6 thus has three functions, an aesthetic function, a function of limiting the axial displacements of the column wheel 1 in the event of shocks and a function of adjusting the penetration of the teeth of the intermediate wheels 13 and the chronograph 15.

Le mécanisme est ainsi simplifié par l'abandon de l'excentrique généralement utilisé pour le réglage de la course de la bascule d'embrayage.The mechanism is thus simplified by abandoning the eccentric generally used for adjusting the stroke of the clutch rocker.

Enfin, le réglage de la course de la bascule d'embrayage 10 est plus précis car il s'effectue sur le point de la bascule d'embrayage le plus éloigné de son centre de pivotement, le déplacement de l'extrémité du bec 14 est de plus grande amplitude que le déplacement de la roue intermédiaire ce qui permet un réglage très précis. De plus, le diamètre du chapeau 6 de la roue à colonnes 1 est au moins quatre à huit fois supérieur à celui d'un excentrique de réglage habituel, il s'ensuit que la précision et la visibilité du réglage sont grandement augmentées. Ce réglage est également plus progressif et donc plus facile à effectuer.Finally, the adjustment of the stroke of the clutch rocker 10 is more accurate because it is performed on the point of the clutch lever farthest from its pivot center, the displacement of the end of the spout 14 is greater amplitude than the displacement of the intermediate wheel which allows a very precise adjustment. In addition, the diameter of the cap 6 of the column wheel 1 is at least four to eight times greater than that of a usual control eccentric, it follows that the accuracy and visibility of the setting are greatly increased. This setting is also more progressive and therefore easier to perform.

Enfin, l'ovalisation du chapeau 6 de la roue à couronne est invisible à l'oeil nu, car la différence entre le grand et le petit diamètre extérieur est typiquement de l'ordre de quelques centièmes de millimètres, par exemple de 0,03 à 0,08 mm.Finally, the ovalization of the cap 6 of the crown wheel is invisible to the naked eye, because the difference between the large and the small outer diameter is typically of the order of a few hundredths of a millimeter, for example 0.03 at 0.08 mm.

On remarque encore que pour le réglage du mécanisme de chronographe, il suffit de retirer le chapeau 6 de la roue à colonnes 1 (fig. 5) et de le remplacer par un tube de travail 20. L'horloger peut alors faire tous les réglages nécessaires du mécanisme de chronographe puisque la roue à colonnes 1 est visible et accessible depuis le dessus. Une fois le réglage du mécanisme effectué le tube de travail 20 est enlevé et le chapeau 6 de la roue à colonnes est mis en place. Avant de serrer la vis 7 on procède au réglage de la pénétration de la denture de la roue intermédiaire 13 dans la denture de la roue de chronographe 15 en faisant tourner le chapeau 6 de la roue à colonnes autour de son axe puis il est bloqué en position par le serrage de la vis 7.Note also that for setting the chronograph mechanism, simply remove the cap 6 of the column wheel 1 ( Fig. 5 ) and replace it with a working tube 20. The watchmaker can then make all the necessary adjustments of the chronograph mechanism since the column wheel 1 is visible and accessible from above. Once the adjustment of the mechanism is done the working tube 20 is removed and the cap 6 of the column wheel is put in place. Before tightening the screw 7, the penetration of the toothing of the intermediate wheel 13 into the gearing of the chronograph wheel 15 is adjusted by rotating the cap 6 of the column wheel about its axis, and then it is locked in position. position by tightening the screw 7.

Dans des variantes le chapeau 6 de la roue à colonnes 1 pourrait présenter une circonférence périphérique excentrée plutôt qu'ovalisée le résultat serait le même. D'une façon générale il suffit qu'une partie de la circonférence du chapeau présente une distance à son centre qui varie en fonction de son orientation angulaire pour que ledit chapeau constitue une came de réglage de la position du bec 14 de la bascule d'embrayage lorsqu'il se trouve entre deux colonnes 2 de la roue à colonnes 1.In variants, the cap 6 of the column wheel 1 could have an off-center peripheral circumference rather than an equilibrium the result would be the even. In general, it suffices that a portion of the circumference of the cap has a distance to its center which varies according to its angular orientation so that said cap constitutes a cam for adjusting the position of the spout 14 of the latch. clutch when it is between two columns 2 of the column wheel 1.

Dans une variante illustrée la figure 8, le chapeau 6 de la roue à colonnes peut présenter, vu de dessus, une forme circulaire mais comporter sur sa face inférieure un bossage excentrique 21 dont la surface périphérique 22 sert de came de réglage coopérant avec la face d'appui 16 du bec 14 de la bascule d'embrayage 10.In an illustrated variant the figure 8 , the cap 6 of the column wheel may have, seen from above, a circular shape but have on its underside an eccentric boss 21, the peripheral surface 22 serves as an adjustment cam cooperating with the bearing face 16 of the spout 14 clutch lever 10.

D'une façon générale, le dispositif de réglage de la pénétration de la denture de la roue intermédiaire 13 dans la denture de la roue de chronographe 15 comporte d'une part une face d'appui 16 portée par le bec 14 de la bascule d'embrayage et d'autre part une came 17; 21,22 pivotée concentriquement à la roue à colonnes 1, de préférence mais non obligatoirement intégrée au chapeau 6 de cette roue à colonnes 1.In a general manner, the device for adjusting the penetration of the toothing of the intermediate wheel 13 into the toothing of the chronograph wheel 15 comprises on the one hand a bearing surface 16 carried by the spout 14 of the rocker d clutch and on the other hand a cam 17; 21,22 concentrically pivoted to the column wheel 1, preferably but not necessarily integrated in the cap 6 of the column wheel 1.

Cette came dont la position angulaire détermine la pénétration de la denture de la roue intermédiaire 13 dans la denture de la roue de chronographe 15 est située au moins partiellement au-dessus de la roue à colonnes, et peut être fixée dans la position angulaire désirée, par exemple à l'aide d'une vis. Cette came est de préférence concentrique à la roue à colonnes 1 et dans la forme d'exécution préférée intégrée au chapeau 6 de cette roue à colonnes 1.This cam whose angular position determines the penetration of the toothing of the intermediate wheel 13 in the toothing of the chronograph wheel 15 is located at least partially above the column wheel, and can be fixed in the desired angular position, for example using a screw.
